VEHICLE-AXLE.

SPECIFICATION forming part of Letters Patent No. 334,566, dated January 19. 1886.

Q I Application filed August 24, 1885. Serial No.175,209. (No model.)

To all whom, it may concern.-

Be it known that I, HERBERT M. CLARK, a citizen of the United States, residing in the city of Oshkosh, in Winnebago county, in the State of Wisconsin, have invented new and useful Improvements. in Axles and Axle- Boxes for WVheeled Vehicles, of which the following is a specification.

My invention consists of a spiral groove or grooves turned in either the outside surface a of axle'collar, inside surface of axlebox covering axle-collar, or in both.

Many devices have been brought out and patented to overcome the difficulty which my invention will; but they have one and all failed to accomplishthe desired end by reason of faulty principles in their construction.

In the accompanying drawings, Figure 1 is a view in side elevation of a section of an axle and an axle-box, showing in dotted lines grooves on the inner face of the axle-box. Fig. 2 is a view of the axle, showing the grooves formed on the periphery of the axlecollar. Fig. 3 is an end view of Fig. 2, the axle-box being in position thereon; and Fig. 4 is an end view of the axle-box, showing grooves on the inner face thereof.

A represents the axle, B the axle-spindle,

and O a collar located at thejunction of theaxle and spindle. This collar rests snugly within asiniilarly-shaped recess or seat formed at the inner end of the axle-box B, and is provided on its periphery with a series ofgrooves,

d, so shaped and disposed as to direct any dust or grit entering between the collar and box at this point'outwardly or away from the collar and box as the latter is revolved.

Instead of forming the grooves on the periphery of the collar, as shown in Figs. 2 and 3, they can be formed on the inner face of the axle-box B, as shown at e, Figs. 1 and 4; or the grooves can be formed on both and answer the same purpose. I

It will be readily seen that when the axlebox revolves by motion of wheel around axle in direction of arrow B in Fig. 2 the tendency is to carry all sand or grit which may be thrown against end of axle-box on axle outwardly in the same manner as an anger or drill throws out chips and shavings in boring ahole.

Having now fully described my invention, what I claim as new, and for which I desire to secure Letters Patent, is-

1. The combination of an axle having acollar thereon and an axle-box constructed to receive and closely encircle the collar, the said collar or box having a series of grooves, arranged substantially as described, and terminating at the inner end of the hub, whereby sand or grit is carried by the grooves and discharged from the hub, substantially as set forth.

2. The combination, with an axle having a collar, the latter provided on its periphery with a series of short grooves, arranged substantially as described, and passing through the outer face of the collar, of an axle-box the inner end of which snugly encircles the collar, substantially as set forth.
